To nest a decision under an outcome, drag another decision symbol from the library and modify it to fit into the table cell. Then select the rows under the decision symbol and choose Split Cells under the Table menu.


Keep joining and splitting cells until your table is fully formatted. If you have an uneven decision, you can move the gridlines into place to match the decision divisions. To do so, click on the gridline to select it (this should make the gridline turn a light green color) and drag it with the mouse.
